in server/{config}/deploy

Thanks
I updates the user-service.xml as follows
<!--
| Add custom MBeans here. MBeans should be registered under the
| 'user' JMX domain, or a domain specific to the component application.
|
| Do not place user components in the 'jboss' domain or any sub-domain.
-->
<!-- Example Service Configuration
AttributeValue
-->
<!-- ==================================================================== -->
<!-- Startup class - Added by Arvind on 10/04/2002 -->
<!-- ==================================================================== -->
JbossStartup
C:\\WINNT\\halogenapp.ini
C:\\WINNT\\halogenapp.ini
What does the following sentence mean
MBeans should be registered under the
| 'user' JMX domain, or a domain specific to the component application.
How do I do register mbean?.Sorry to bother you,asI don't have acces to any form of documenation to findouut these details.
Thanks,

3. Re: Startup class
adrian.brock Oct 4, 2002 6:42 PM (in response to arvindbc)The service controller does the registration using
the name
user:service=JbossStartup
you might want to use
com.sungard:service=JbossStartup
you could even create a
sungard-service.xml in server/default/deploy

When I start Jboss I get this error
rver/default/deploy/jms-service.xml
17:53:56,453 INFO [MainDeployer] Starting deployment of package: file:/C:/Java/
jboss-3.0.3/server/default/deploy/user-service.xml

In fact the comments in the user-service.xml says
<!--

| Do not place user components in the 'jboss' domain or any sub-domain.

But I don't know what I have to do.
I greatly appreciate your patience and help.

5. Re: Startup class
adrian.brock Oct 5, 2002 8:42 AM (in response to arvindbc)This is the second time somebody has reported
something like this, the error reporting seems a bit
crock.
Your JBossStartupClass is deployed in jar somewhere?
Your JbossStartupClass is an MBean?
If it is a standard mbean, the attributes normally
start with uppercase letters.
Is there any extra info in server/default/server.log?

My startup class is deployed as jar in server\deploy\lib directory,and it is a standard MBean.
I made some changes to my user-service.xml and my Mbean after having better understanding from your rsponses and also some of the reading I did on MBeans.If you see my code, I am loading some configurations in init() method.Is my understanding that this init() method gets called while registering this Mbean , correct?
I am attching interface of MBean,implementaion,user-service.xml,and the error I am getting.I checked log, it contains the same stack trace as is in the attached screen shot.
Thanks,

8. Re: Startup class
juha Oct 7, 2002 12:04 PM (in response to arvindbc)you need to declare your management attributes (that you use in user-service.xml) in your MBean interface class as well

9. Re: Startup class
arvindbc Oct 7, 2002 12:34 PM (in response to arvindbc)Thanks, it did help.I overlooked that,sorry for the trouble.
Is my assumption that init() method I defined in Mbean gets called automatically,correct?.It was true in Jboss-2.4.6_Tomcat-4.0.3.If that is not so in case of Jboss-3.0.3, then how could it be done.My main purpose of this Mbean is to call a application intialization class at server startup time.If you see my code attached in the previous mail , you may see I am calling main method of FrameWorkConfig class.
When are the attribute values from user-service.xml get loaded into MBean?.I tried to print the attribute values in MBean constructor, hey are null indicating that they are not loaded when the MBean object is constructed.
Thanks
Arvind -
10. Re: Startup class
juha Oct 7, 2002 2:00 PM (in response to arvindbc)after construction, the MBean needs to be instantiated and registered to the MBean server before setAttribute can be called
-
11. Re: Startup class
arvindbc Oct 8, 2002 10:58 AM (in response to arvindbc)I am specifying the MBean in user-service.xml,so I understand the registartion of the MBean should be taken care by Jboss startup,and the attribute values loaded.Is that correct?.In the xml file I am also specifying the attributes.Section of user-service.xml is
C:\\WINNT\\halogenapp.ini
DEFAULT
Thanks.

adrian.brock Oct 8, 2002 11:25 AM (in response to arvindbc)>Is my assumption that init() method I defined in Mbean gets called automatically,correct?.
It was changed to create() in jboss3,
it better describes what it does.
preRegister is for initialization (before attributes
are set)
If you need it to work in both versions.
public void create()
{
init();
}

mike.pettit Nov 7, 2002 12:35 PM (in response to arvindbc)Hi -
this thread has been very useful. I am trying to do the same thing, but my create() and/or init() methods are not being called automatically. Any clues on that?
Also, I am doing some stuff with my database and my MBean is being loaded before my datasource is bound. doesn't seem to work in my user-service.xml... any clues?
